SHUTTLE-PLANER.

SPECIFICATION forming part of Letters Patent No. 412,930, dated October 15, 1889.

Application filed May 27, 1889. Serial No. 812,252. (No modeL) To all whom, it may concern:

Be it known that I, JOHN M. NEWTON, a citizen of the Unit-ed States, residing at Norwich, in the county of New London and State of Connecticut, have invented a certain new and useful Improvement in Shuttle-Planers, which improvement is fully set forth and described in the following specification, reference being had to the accompanying sheet of drawings, in which- Figure 1. is a side elevation of aplaner embodying my said invention, the bed section being partly cut away to expose a shuttle held therein. Fig. 2 is a cross-section of a similar bed, considerably enlarged, taken on line on 9:.

This invention is in that class of shuttleplaners in which the-shuttle is held on centers, one of which is usually astrong thumbscrew, the side of said shuttle being trued up by means of a finely-adjusted plane that slideson said bed, as 011 ways.

The particular purpose of this present invention is to provide, in connection with such a shuttle-planer, simple and inexpensive devices by means of which a shuttle may not only be squared up, but may as readily be tapered or beveled, if desired. Many of the shuttles used in weaving are so beveled to overcome, in a measure, the tendency and liability to jump upward and out of the shut tle-race as they shoot ahead. The. slight bevel thus provided leaves the bottom-of the shuttle a little wider than the top, thus enabling the shuttle-box brake-spring to hold said shuttle down in the race as said shuttle passes under said spring.

In truing up a pair or set of shuttles for use in the same loom it is desirable that they be exactly the same size, weight, and bevel, so that when a full shuttle is substituted for an empty one there will be no appreciable difierence in the tension and texture of the woven fabric. The device which I have provided, and which I will proceed to describe, when once adjusted enables the operator to true up and bevel a multiple of shuttles, so that they are all practically alike.

Referring to the drawings, the letter a indicates the bed of my shuttle-planer, having feet or standards I) b, and having its upper side planed up to form ways on and between which a plane 0 may travel. Said plane is supported on each side bybars cl, that are attached to the main frame or shoe of the plane by links 6. The bars 01 are joined at one end to a crosshead f, that is slotted vertically, and in the slot thus provided is a thumb-screw h, whose inner threaded end is tapped into a rigid portion of the plane. When said thumb-screw is rotated, the bars d are moved endwise, (substantially like one member of a parallel ruler,) and as a result the plane rises and lowers between the ways of the bed, according to the direction of ro tation of screw 7L. By this adj ustmentof the plane the depth ofcut may be controlled.

At one or both ends, if desired, of bed a is a strong thumb-screw 2', whose inner end is cupped to support one end of the shuttle. The opposite end of said shuttle maybe held in a cup-center formed in the bed, as shown in Fig, 1. To hold the shuttle against rotation on its centers,athumb-screw 10, having a loose washer on its inner end, is tapped into bed a on one side, preferably about midway of its length. The clamping devices thus provided are sufficient to hold the shuttle rigidly in position while being squared up. Then it is desired to bevel the side of a shutt-le, other devices are added, as follows: A bar m is secured to the under side of bed a by bolts or screws m, one of which may consist of a thumb-screw, as shown in Fig. 2, and for a purpose hereinafter explained, After a shuttle n has been secured between the de scribed centers, a wedge 0 is forced between the bar m and the lower face of the shuttle. This wedge may be tapered transversely as well as longitudinally, and when forced home rocks the shuttle on its centers, throwing the upper face of the shuttle, which is to engage the cutting bit, slightly out of a horizontal plane. The same result may be attained by means of a wedge of ordinary shape-that is to say, one tapered only in its length-by unscrewing the thumb-screw m and allowing one end of the bar m to drop slightly away from the bed.

The wedge 0, when forced into place, not only serves to adjust the shuttle to producea bevel cut, but also provides a solid backing IOG 1. In a shuttle-planer, in combination with a bed having centers, as set forth, for sup porting a shuttle, a cross-bar secured to .the

. under side of said bed, and a Wedge inserted IO between said bar and the shuttle, substantially as and for the purpose specified.

2. A bed having centers, as set forth, for supporting a shuttle, and a cross-bar attached to the under side of said bed and having one end Vertically adjustable, as described, in combination with a wedge insert-ed between the saidcross-bar and shuttle, substantially as and for the purpose specified.
